Mickelson's tweet - apparently, he grabbed his trusty iPad on the way out - confirmed that he fleed the hotel without his clubs and clothes and in danger of missing his Sunday tee time. Golfweek's Steve DiMeglio reports that firefighters helped him back into his room to get his belongings, and he was able to make it to the course with time to spare.
However, the 49 year old arrived in flip flops and was photographed taking practice swings in the parking lot as he rushed to prepare for his round.
"EMT's were awesome! I'm going to make it. Turns out my clubs acted as a fire retardant".
He told her at one point, "I tweeted it".
Tee times had been moved back due to forecasted thunderstorms on Sunday morning, with American Justin Thomas holding a six-shot lead heading into the final round.
